Optoma UHD30 True 4K UHD Gaming Projector - 16ms Response Time, Enhanced Gaming Mode, Lowest Input Lag, 240Hz Refresh Rate, HDR10 & HLG - Perfect for Home Theater, Gaming, and Movie Nights

I had been looking to get a projector for a while. I am one of the few people who still enjoyed 3D at home, and projectors are pretty much the only way you can get that. I didn't want a 'cheapo' and I didn't have the money to drop for one of the extreme ones, this one came in right where I needed. This is also a true 4k picture, whereas many of those out there take 4k input, but don't display 4k, only 1080P. The 3D is only 1080, but that is a limitation of the format, not the device.A few things I did not know to look for, but would seek out. - BluTooth connectivity for sound. I had to buy a blutooth transmitter to go to my blutooth soundbar. This was a necessary thing as the sound settings built into this projector are horrible. at its lowest setting it was still too loud when playing games. That being said, it has output for sound that I could use with a blutooth transmitter and that works well with the soundbar I have, but it does make for another item to turn on every time. Look for a soundbar or sound device you can tweak, as there is a slight delay going all the way to the projector and then out the blutooth. Setups where the sound goes to the speakers before going to the projector should work fine.This device has 1 HDMI2 and one HDMI3. Wouldn't mind a few more connections, but with a few adapters, which I'd need anyway, it works fine. That being said, this device does not 'turn on' when you use an HDMI device, as some others do, so have to keep track of that remote for the projector. Minor inconvenience really.Those are the only real detractors. Picture is amazing and bright, can watch with the lights on, or windows open no problem. 3D is easy to switch to and a pleasure to watch. 4k is easily recognized from input (blueray) and screen adapts seamlessly. No appreciable sound from the device to interfere with viewing. I have mine mounted from the cieling. Easily setup to project picture in proper orientation. I have mine about 10 ft from the screen, and at about 100" Will work further back if you want a larger picture.All in all, solid 4 1/2 to 5 stars. Well worth the price.
